For antioxidant defense, detoxification, and cellular protection, this delivers 500mg of **reduced L-Glutathione** per capsule — targeting your body's primary antioxidant system. Clinical studies on oral glutathione have used doses ranging from 250–1,000mg/day, putting this at the midpoint of the studied range.
The "reduced" form (GSH) is the biologically active version, which matters — oxidized glutathione can't perform the same antioxidant functions until your body converts it back. At one capsule daily, you're getting a meaningful dose without needing to take multiple pills.
The main caveat with oral glutathione is absorption. Your digestive system breaks down a significant portion before it reaches your bloodstream. Some research suggests liposomal or sublingual delivery may improve bioavailability. If you're specifically trying to raise glutathione levels, pairing with NAC or vitamin C may be a more reliable approach.
